yReferring to the various views in Figure 1,A 8 generally, designates a building structure partly broken in order to facilitate depicting the essento providei3,y having zahandle t5 suitable for carrying the same, it having'also a protecting coverfil' in' order to :shield-.the opening o'f the said receptacle .I3 from receiving the rain water directly, the rain Water being fed thereinto, primarily, after it has run down the drain pipe It, ltered through my devicacgeneraily, Vdesignated lf2; into' ythereceptacle 'I3 r`so thatltered rain water rmay be thus kept clear oifthe rain' drops ywhich would tend to 4contaminate the filtered water #strained -My-rdevice.rests-'Ondine ground surface M, its legs' I8 having feet portions 19. secured 'byfvirtu'e ofbolts'20 or similarfastenings'.

' `In Figures 2f, 3 and 4, I 'show one :form foi' myxinvfentionr which is comprised 'of the body ,121 havingfa'threaded inlet vportion 22 .adapted to be secured to a drain-pipe Ill by virtue offthe adapter fitting II.L The ybody may ber made of cast metalA 'or any `other suitable material and isprovided with sa' number lof alternately positioned baie plates designated 23',A 2.4, -25 and 26.

rThe receiving well 29 for the rain water vor liquid isiinterconnected through the screened opening .28 with the lpartitioned chamber containing the 'comminu'ted material 2,1 which may be sand orany other suitable lltering material which is packed down tightly, however not soas to fill thefpafrtitioned compartment, thus` allowing the water -to circulate and filter through the com minuted material,A the path taken by the -liquid tial structure of my invention. The gutter 9 is mounted on the eaves, and it is in turn connected material from being drained off with the water or Washed away therewith.

The body is provided with an opening at the top near the surface 36 upon which is mounted the gasket 35 and the cover plate 34 held securely in place by virtue of screws 32 and lock washers 33.' The lower portion or the bottom is providedv with two openings having a bayonet lock joint 39 adapted to receive'the caps 31 provided with the convenient hand grips 38 to permit removal thereof which it is desired to remove the fouled sand, preparatory to lling with fresh filtering material. I

The form shown in Figures`5, 6 and 7 `is similar to the form shown in Figures 2, 3 and 4 with the exception that the body, generally, designated 40 has a web portion with an opening 4I in order to receive an inner member, generally,

seams designated 42, the hub 43 thereof iitting into the said recess 4|, while one end of the said body 40 is slotted at 41 in order to per-mit the outlet 46 to be slid down therein and thus permit the bearing portion 43 to fit within the recess 4l to make a water-tight connection as shown in Figure 5. rPhe member 42 is similar in construction internally as body 2l, that is, in having alternate web portions 24, and 26 and a quantity of comminuted material as well as the strainer or wire mesh elements 44 and 45, similar to elements 28 and 3U in the form shown in Figure 2. It is likewise provided with a top plate 34, a gasket 35, and screws 32 and lock washers 33.

The body or the outer container 40 has a solid bed portion 48, because in this particular instance, when it is desired to change the com` minuted filtering material which has become contaminated with foreign matter and impurities, the inner body 42 is removed from the outer casing 40 permitting body 42 to be upset or overturned discharging the fouled comminuted material 21. New comminuted material is then placed therein and the device is then ready for continued filtering action.

Although I have indicated an application of my particular invention in connection with iiltering rain Water, it is to be understood, that my invention can be used in any liquid feeding sys tem, which may require filtration action. It also may be used in connection with sewage systems, or any other systems, wherein my invention would specifically apply and operate emciently, moreover, it may be used in chemical laboratories, as well as many other similar uses and applications to which my invention may be adapted.

Even though I have described and revealed rather succinctly my invention, I recognize that it is susceptible of modification, alteration, and improvement, hence, I reserve the right to all modifications, alterations, and improvementsk 1. In a liquid filtering device of the character described, body means consisting of a bottom, two side walls and two end walls being open at the top and provided with inlet means adjacent one end wall and terminating in Van enlarged opening, and also provided with a slotted portion open at the top and located on the end wall of said body means opposite the said enlarged opening, and filtering body means removably secured to the said body means, the said filtering body means provided with inlet means adapted to locate within the said enlarged opening, and fur ther provided with outlet means adapted to locate within the said slotted portion, the said ltering body means being of a coniiguration adapted to nest within the said body means, the compartment of the said iiltering body means being provided with alternately disposed bafiie plates adapted to cause a liquid to be circulated therethrough in a sinuous path.

2. A liquid ltering device of the character described, comprising an outer body element consisting of a bottom, two end walls and two side Walls being open at the top and provided with inlet means adjacent one end wall and. terminating in an enlarged opening, and further provide with a slotted portion open at the top and located on the end wall of said outer body element opposite the said enlarged opening, an inner iiltering body element provided with inlet means adapted to locate within the said enlarged opening, and further provided with outlet means adapted to locate within the said slotted portion, a compartment in said inner ltering body element provided with alternately disposed bafe plate means and being partly filled with comminuted material adapted to cause a liquid to iiow therethrough in a sinuous path, strainer means secured within the compartment of the said inner filtering body element at the said inlet and outlet means, a coverelement adapted to seal the said compartment and retain the assemblage of the said outer body element and the Vsaid inner filtering body element, the said inner filtering body element being of a configuration adapted to nest within the said outer body element, and fastening means adapted to secure -the said cover element and the said inner ltering body element within the said outer body element.
